// DESCRIPTION
|

|
//
|
||
|
// ASCII FORMAT
|
||
|
//
|
||
|
// The ASCII description is a string with fields separated by tabs or
|
||
|
// white space. It is made of the ASCII description of a
|
||
|
// <i>WordKey</i> object immediately followed by the ASCII
|
||
|
// description of a <i>WordRecord</i> object. See the corresponding
